 Muscular
Dystrophy is an inherited
disorder where your muscles weaken
and tissue is loss.
 It continually gets worse over time.
 Guillaume
Benjamin Amand Duchenne
discovered Muscular Dystrophy.
 It was discovered in the 1860’s in Paris.
 He described 7 progressive muscle
weakness in 13 young boys.
 It was later called Duchenne Muscular
Dystrophy after Benjamin.
 Difficulty
using one
or more muscle
groups
 Muscle weakness that
slowly gets worse
 Frequent Falling
 Loss in muscle size
 No
cure
 Treatment is used to
prevent symptoms.
 Physical therapy can
help keep muscle
strength
 Braces improve
mobility
 Staying active is key,
bed rest could make
the disease worse
 Doctors
use your past medical records and
physical examines to determine if someone
has muscular dystrophy and what type.
 Some types are:
• Becker muscular dystrophy
• Duchenne muscular dystrophy(most common in
children)
• Emery-Dreifuss muscular dystrophy
• Limb-girdle muscular dystrophy
• Myotonic dystrophy(most common in adults)
A
Muscle Biopsy or DNA blood tests can
affirm the diagnosis.
It is passed down
through families by an
affected gene.
 Different types are
passed down different
ways.
 Limb-girdle dystrophy
is autosomal recessive
 Duchenne dystrophy is
a defective gene
carried by the female
and transmitted to the
male.
 Each type affects a
different gene.

1
in 3 thousand
children are born
with Duchenne
muscular disease.
 Average lifespan for
those with Duchenne
MD is about 20 years,
but those with Becker
MD can have a
normal lifespan.
